Welcome Aboard, Robyn!
The Western Caribbean Itinerary is one of my favorites with Disney Cruise Line! I have sailed this itinerary three times, twice on the Disney Magic and once on the Disney Fantasy.
In Cozumel, I have participated in the
Dolphin Swim at Dolphinaris - All Inclusive port adventure with my family. At the time, my daughters were 7 and 10, and the girls loved in almost as much as I did! We wore life jackets, and went into some deep water with the dolphins.
If you love marine life as much as I do, I would highly recommend booking the
Island Tour and Snorkeling with Stingrays port adventure in Grand Cayman. It was probably the best port adventure that we have ever done! We loved going to see the sea turtles at the Cayman Islands Turtle Farm and then heading out to the Stingray Sandbar to interact with the stingrays in their natural environment.
I hope this helps with your cruise planning! Please let me know if the Disney Parks Moms Panel can answer any other cruise planning questions!
Happy Cruising, Tracy V.
